An afterloading technique suitable for carcinomas of the oral cavity.

The authors describe an afterloading brachytherapy to treat oral cavity carcinomas. Catheters for arterial/venous catheterization are inserted percutaneously in the target volume. The internal needles are then removed and replaced with iridium wires inside tubes to form wire loops.

[Influence of radiotherapy on lymphocyte subpopulations].

The authors investigated the effects of radiation therapy on the immune system by studying lymphocyte subsets and other parameters in 32 patients undergoing radiation therapy for solid cancer. With monoclonal antibody techniques, we studied both T- and B-lymphocytes; cell suspensions were analyzed by means of a Facs Spectrum III Ortho (Ortho-Diagnostic) unit. The first control was performed right after the beginning of radiotherapy, when the dose to the patients was 50 Gy or higher.

[Role of accelerated electrons in the therapy of advanced-stage skin epithelioma advanced stage: analysis of 31 cases].

Electron beam therapy is the superior modality of treatment for advanced skin cancer or in specific anatomical situations. The authors report the results for the electron beam therapy of 31 patients with advanced skin carcinoma. There were 15 squamous cell carcinomas, 11 basal cell carcinomas and 5 mixed, basosquamous cell carcinomas.

[The treatment of cancer of the anal area with radiotherapy. An analysis of the authors' personal experience].

The treatment of anal canal carcinoma is very difficult and great care must be taken in planning therapy because this type of cancer is potentially curable. From 1982 through 1989 we treated 16 patients with carcinoma of the anal canal. All patients were evaluable for toxicity and 14/16 for response after treatment.
